Cat-Paw Pad Bionic Design of Motorcycle Tire Crown

  • 摘要: 二轮摩托车轮胎接地面积很小,其接地性能直接影响车辆的动力性、制动性以及操纵稳定性。针对这一问题,对摩托车轮胎胎冠进行了仿生设计。利用WALKWAY压力分布测试系统和3D激光扫描仪对猫爪的动态接地特性及拓扑进行研究,发现猫前爪第三趾枕具有优异的抓地性能。基于第三趾枕横截面拟合曲线采用相似原理对轮胎胎冠进行了仿生设计。利用ABAQUS对轮胎进行静载、驱动、制动及转向接地状态仿真分析。结果表明:不同工况下,仿生轮胎胎冠接地面积增大,接地压力分布均匀性提高,轮胎的抓地及耐磨性能都得到提升。仿生轮胎提高了摩托车的动力性、制动性以及操纵稳定性。
